I've just gone back to the darkside and purchased an 427FE powered Ford and now upgrading a few powertrain components for peace of mind. The car is still in the USA and will hopefully arrive downunder corresponding with my return home after Deuce Day. Anyway I'm swapping out the current cast iron bellhousing to an older period correct NHRA approved aluminum scatter shield (RC industries). Since I'm at it, I'll update the current clutch and flywheel as well to SFI rated, similar to crankshaft balancer. I might as well install ARP fasteners at the same time. Anyway I've now got a new 11" Hayes pressure plate, clutch disc and throwout bearing however I'd like to upgrade to an SFI flywheel and have been advised that a 460 Ford flywheel will also work as it has same bolt pattern, tooth count as well as being internally balanced. Hayes have 2 x listing with different numbers, FEs and 460s. Throwing it out there for those in the know as I propose to use the OEM Bendix starter or whatever is in car, any thoughts as I've come across a good used Hayes flywheel that I can throw in the car for shipping and save on additional freight.
